Rémi Bernon 8a765533d6 ntdll: Implement zero_bits parameter in virtual alloc functions.
Use alloc_area.limit field to limit the search in reserved areas to the
desired memory range, or call find_free_area to get a pointer to a free
memory region which matches the zero_bits constraint, then mmap it with
MAP_FIXED flag.

Rémi Bernon 6672fc9d85 ntdll: Use custom internal zero_bits_64 parameter format.
The zero_bits parameter can be a pointer mask on Win64 and WoW64 and it
was incorrectly truncated to 16bits in APCs. Testing shows that only the
leading zeroes are used in the mask, so we can safely use the 64 based
number of leading zeroes everywhere instead.

Rémi Bernon d1a7b681ea ntdll: Change zero_bits parameter type to ULONG_PTR for NtMapViewOfSection and NtAllocateVirtualMemory.
It can be a pointer mask, eventually 64bit, and ULONG_PTR is what can be
found in several documentation of these functions.

Rémi Bernon 1aa963efd7 ntdll: Add alloc_type parameter to virtual_map_section and top_down to map_image.
NtMapViewOfSection also accepts the MEM_TOP_DOWN parameter that can
be used in combination with zero_bits to map memory on the highest
possible address.

Rémi Bernon 00451d5edf ntdll: Clarify NtAllocateVirtualMemory zero_bits parameter semantics.
This parameter was misinterpreted as an alignment parameter for the
lower bits of the allocated memory region, although it is a constraint
on the higher bits.
